Globe at Night - Nightly

Night Sky Survey - Nightly Night Sky Survey A thorough Night Sky Survey is essential to a successful application to the International Dark Sky Places program. There are a variety of ways to approach it and improve upon it. These include: The Sky Quality Meter SurveyThe Bortle Scale InterpretationThe Photographic Evidence Sky Quality Meter Survey This is perhaps one of the easiest ways to achieve quantities measurements of the darkness of your location’s dark skies. It is simple to use and effective at measuring sky brightness at zenith. Using this device a “grid” of the locations may be made. In the map above a suggested method is shown for creating a survey. Bortle Scale Interpretation The Bortle Scale works to estimate sky brightness and interpret how light pollution is affecting your view of night sky phenomenon. This method is less quantitative than the Sky Quality Measurement. Steve Owens, International Dark Sky Places Committee member, is credited with the flow char below. Photographic Evidence
